% 0.61/0.84  % SZS output start Proof
% 0.61/0.84  The input problem is unsatisfiable because
% 0.61/0.84  
% 0.61/0.84  [1] the following set of Horn clauses is unsatisfiable:
% 0.61/0.84  
% 0.61/0.84  	add(X, Y) = add(Y, X)
% 0.61/0.84  	add(add(X, Y), Z) = add(X, add(Y, Z))
% 0.61/0.84  	negate(add(negate(add(X, Y)), negate(add(X, negate(Y))))) = X
% 0.61/0.84  	negate(add(a, negate(b))) = c
% 0.61/0.84  	negate(add(c, negate(add(b, a)))) = a ==> \bottom
% 0.61/0.84  
% 0.61/0.84  This holds because
% 0.61/0.84  
% 0.61/0.84  [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 0.61/0.84  
% 0.61/0.84  E:
% 0.61/0.84  	add(X, Y) = add(Y, X)
% 0.61/0.84  	add(add(X, Y), Z) = add(X, add(Y, Z))

% 0.61/0.84  	negate(add(negate(add(X, Y)), negate(add(X, negate(Y))))) = X
% 0.61/0.84  G:
% 0.61/0.84  	true__ = false__
% 0.61/0.84  
% 0.61/0.84  This holds because
% 0.61/0.84  
% 0.61/0.84  [3] E entails the following ordered TRS and the lhs and rhs of G join by the TRS:
% 0.61/0.84  
% 0.61/0.84  	add(X, Y) = add(Y, X)
% 0.61/0.84  	add(Y1, add(Y0, Y2)) = add(Y0, add(Y1, Y2))
